Windows are crucial parts of a home. They provide daylight, outdoor views, and natural ventilation. When broken, replacing these components typically takes four to 15 weeks, while the actual installation labor only takes between 30 minutes and one hour.

Faulty windows pose security risks and increase energy costs for your household. So, if you notice drafty signs of wear and tear, it’s best to start budgeting for those replacements.

But exactly how long does it take to install replacement windows in your case? Our comprehensive guide will walk you through all the factors you should consider, including some practical tips that may save you more time and money.

Factors to Consider When Replacing Windows

Installing replacement windows can take four to 15 weeks from the day you decided to update your home to the installation date. Some factors that may affect the timeline include:

Window Type

There are different types of windows used in residential homes, and, depending on their complexity, they can add a considerable amount of time to the installation process.

If you’re replacing a custom window, your contractor must order the replacement components and wait for the manufacturer to make and ship them. Specially manufactured designs typically take longer than standard models.

Another consideration is the window material. For instance, wood windows generally take more time than, say, vinyl, because they need to be prepped more intensively (sanded, primed, painted, etc.).

Window Size

One of the more obvious factors for added installation time is your window size. While bigger windows provide more light and enhanced outdoor views, they’re usually heavier and more complex. Not to mention the extra time it’ll take to modify the wall to accommodate them.

Whether you need a retrofit or a full-frame installation service can also affect the project’s timeline.

A retrofit installation means the contractor will replace the window sash of an existing frame, without disassembling the entire frame or altering any part of your home’s exterior. This is usually more affordable and less labor-intensive.

However, retrofit replacements aren’t recommended for older homes, as they won’t address any damage underneath the original frame.

Full-frame installations are more involved and time-consuming. That’s because the contractor will replace every part of the deteriorating window, including the frame, brick molding, and more.

Still, while usually more expensive, a full-frame installation allows your contractor to repair mold, mildew, and water damage. This makes your home more energy-efficient with fewer maintenance requirements.

Window Frames

The window frame supports the entire weight of the structure. The frame type you want installed can affect how fast the renovation goes.

Aluminum and vinyl are both cost-friendly framing options that are easy to install. They’re lightweight and low-maintenance, which means quicker fitting time and greater savings in the long run.

Steel and fiberglass frames are heavier and less forgiving, so your contractor may take more time fitting them. They’re also usually more pricey, costing from several hundred to over a thousand dollars.

Steel and fiberglass frames are among the most long-lasting materials you can get. They’re incredibly durable against the weather and are more energy-efficient than vinyl and aluminum.

Number of Windows

A professional installer should take between 30 and 60 minutes to install a standard-sized window. Naturally, the more windows you want replaced, the more time it’ll take to complete your renovation project.

This is why choosing your contractor wisely is important if you want to save time. A skilled contractor should be able to fit 10 to 15 windows in one day.

Structural Damage

Window damage increases the cost and extends the overall replacement time. The more severe the damage, the more intricate the removal and installation become.

Water damage is common and caused by liquid seeping into the window structure. This causes warping, cracking, and decaying, compromising your home’s security and energy efficiency.

If you notice mold, mildew, and black fuzz growing around your windows, be prepared for a lengthy replacement installation.

Location (Home vs Apartments)

Do you live in an apartment that is several stories up? Do your windows have plant fixtures or heavy furniture blocking the way? Your location and environment can affect how quickly your installer can replace your windows. 

A competent contractor will know to prioritize safety protocols in these instances, which can take time during installation. Ensure to communicate these factors with the window companies so they can give you a clear timeframe.

Depending on your area, you’ll likely need a permit for these home improvement projects. You may also need permission from your local homeowners’ association, so put in your request as soon as possible to shorten the delays.

Signs You Need to Replace Your Windows

What are the signs that you need to replace windows? Be on the lookout for these faulty window warning signs:

Indoor Drafts

Do you feel cool drafts inside your home even though you’re sure your windows are closed? Or perhaps you hear whistling despite locking the window latch? These could indicate gaps or damaged sealing around your window frame.

You can try to remedy the draftiness by caulking, weatherstripping, or window films. But if even those don’t work, it may be time to consider a full-scale replacement.

Foggy Glass

Condensation may seem normal at first glance, especially during winter, but fog forming on the inside of your window means there’s air leaking through your double or triple-paned glass.

While this doesn’t immediately mean you need to replace the entire unit, especially if your frames are still in good shape, it’s a sign that the insulating gas between the glasses has escaped. In either case, you’ll need a professional to address the problem.

More Noise

Apart from moisture and drafts, noise can indicate that you need window replacement. Most modern windows, especially double or triple-paned, should be excellent at blocking outdoor noise.

If you find yourself cranking your TV volume more than usual or repeating your words while talking indoors, it may be time to start budgeting for newer frames.

Visible Damage

This is likely the most obvious sign to upgrade your window. Cracks and warps in the window frame aren’t only unsightly, they also increase the chances of moisture seeping into your property and causing structural damage.

Increased Bills

If you notice a slow but consistent increase in your cooling and heating bill, this is another telltale sign that your windows may need major repairs or replacement. 

Old, rickety windows, in particular, are prone to leaking air, prompting your HVAC system to work harder to keep you comfortable. This strains your heating or cooling equipment and leads to higher energy costs.

This could result in more maintenance expenses over time.
